3D scanning has never been simpler with KIRI Engine: create high-quality 3D models on your phone within minutes. Dive into 3D scanning and modeling tailored for artists, designers, engineers, and 3D printing enthusiasts. Unleash the Power of 3D Scanning: • Photogrammetry: 3D scan with Photo Scan to transform your photos into high-quality 3D models. • NSR (Neural Surface Reconstruction): 3D Scan featureless/shiny objects with a video processed by Neural Radiance Fields (NeRF) integrated Featureless Object Scan. • 3D Gaussian Splatting: Obtain full 3D visualizations with a video, scan and capture all elements in your scene, including reflections. Create Your Own 3D Model through a Delightful Experience: • Capturing: Snapping photos replaces your 3D modeling process, obtain a detailed 3D mesh in just minutes from scanning to generating. • Functional Free Version: Dive into the world of photogrammetry without paying a cent for subscriptions, a LiDAR sensor, or an expensive 3D Scanner. Upload unlimited 3D scans and export at least 3 times per week. Edit, Refine, and Personalize Your Creations: • Edit: Refine 3D models with editing tools; adjust your files in Photo Scan, Featureless Object Scan, and 3D gaussian splats. • Precision: Choose specific photos for processing to ensure detailed, high-quality 3D models. • Cleanup: Auto Object Masking for noise-free, clean models during capture by eliminating background elements. This feature also allows the object to be moved during the capture. • Preview: Employ the 3D viewer and augmented reality panels to directly visualize and adjust your completed 3D model. Share, Export, and Make Use of Your 3D Models: • For Free: free registration and unlimited scanning, with at least 3 exports weekly. • Share: On various platforms such as Sketchfab, Thingiverse, GeoScan, and more. • Formats: Export in OBJ, STL, FBX, GLTF, GLB, USDZ, PLY, XYZ, compatible with Blender 3D, Unreal Engine, Autodesk Maya, etc. • Wide usage: For game development, VFX, VR/AR 3D content creation, 3D printing, 3D visualization, and many more. • Precision Without LiDAR: KIRI’s advanced algorithms provide scanning quality that is on par with LiDAR sensors. KIRI Engine Pro – For Those Who Demand More: • Upload: Pro users can leverage camera rolls, ensuring a flexible 3D scanning experience. • Quad-Mesh Retopology: Refine scanned 3D models with automatic quad-mesh adjustment. • AI PBR Material Generation: Attain lifelike textures with AI-generated PBR materials. • Advanced Camera System: Perfect each shot with fine-tuned camera settings for impeccable 3D scans. • Featureless Object Scan: Utilizes Neural Surface Reconstruction (NSR) for scanning shiny/reflective surfaces, a first in practical 3D scanning with KIRI Engine. • 3D Gaussian Splatting: Experience the future of 3D scanning and capture accurate 3D scenes with a short video; edit using tools like sphere/plane cutters and brushes. Export in native format or OBJ. • WEB Version Access: KIRI Engine WEB offers professional-grade model creation from DSLR photo sets or drone scans, enhancing accuracy in mappings and drone-based 3D surveys.
